ABSTRACT

The aim of this work was to advance the knowledge on the anatomical structure of the sow's udder ( glandula mammaria ) with particular reference to the number of teat glands, their distribution and size as well as the number of teat canals ( ductus papillares ) in each mammilla.

It has been found out that the number of lactiferous ducts ( ductus lactiferi ) goes together with the quality of milk production, it may also affect piglet's preferences in teat choice. It seems worthwhile to conduct selection with the view to uniforming the number of lactiferous sinus and lactiferous ducts in the sow's udder in order to achieve more uniform rearing conditions. The morphometric measurements due to their lack in the literature may be used in further research on the dynamics of swine mammary glands growth in ontogenesis.

Key words: sow?s udder, lactiferous ducts, papillary duct.
